Ground beetles are present in most terrestrial ecosystems and fulfil key functions, especially as many species are important predators, contributing to natural pest control in agricultural landscapes. However, intensive agriculture, which combines monocultures and synthetic inputs, has been shown to have negative effects on insect diversity and abundance. To counteract insect decline, numerous measures are being implemented and tested at national scales. These also include flower strips which might have the potential to provide suitable habitats and connect beneficial insects' populations across agricultural landscapes. Especially if flower strips are located along forest edges, they could reinforce synergy functions and, by that, reduce the barrier effect of conventional agricultural fields. Within the framework of a two-year project, ground beetles were assessed in corn fields [, Linnaeus 1753], grown for biogas production, with or without a two-seed mixture flower strip as well as in the adjacent forest. Study sites were situated within conventional fields typical for the agricultural landscapes in northern German lowlands in direct proximity to the Nature Reserve Lüneburger Heide.
We provide data on 34,413 specimens belonging to 93 ground beetle species. None of these species is evaluated in the IUCN Red List at the European level, but four species have been classified as being within Germany. At the level of the Federal State Lower Saxony, four species are classified as , nine species as and one as , highlighting the importance of this dataset also for conservation purposes.This dataset contributes to the knowledge of Central European carabid diversity and distribution, especially within agricultural landscapes. It supports the development of national and European Red Lists. Despite all sites being placed within conventional corn fields, the study area is in direct proximity to the Nature Reserve Lüneburger Heide where threatened heath landscapes exhibit rare carabid species, which could possibly benefit from adapted agricultural management strategies at its borders or even disperse via suitable corridors provided.
步甲存在于大多数陆地生态系统中并发挥着关键作用，尤其是许多物种是重要的捕食者，有助于农业景观中的自然虫害控制。然而，集约化农业结合了单一栽培和合成投入，已被证明对昆虫多样性和数量有负面影响。为了应对昆虫数量的下降，各国正在实施和测试众多措施。这些措施还包括花带，其可能有潜力提供适宜的栖息地，并连接农业景观中的有益昆虫种群。特别是如果花带位于森林边缘，它们可以增强协同功能，从而减少传统农田的屏障效应。在一个为期两年的项目框架内，对用于生产沼气的玉米田（玉米，林奈，1753）中的步甲进行了评估，这些玉米田有或没有双种子混合花带，以及相邻森林中的步甲。研究地点位于德国北部低地农业景观典型的传统农田内，紧邻吕讷堡石南自然保护区。
我们提供了属于93种步甲的34413个标本的数据。这些物种在欧洲层面的世界自然保护联盟红色名录中均未被评估，但有4个物种在德国被列为受威胁物种。在下萨克森州层面，有4个物种被列为易危，9个物种被列为近危，1个物种被列为数据缺乏，这突出了该数据集对于保护目的的重要性。该数据集有助于了解中欧步甲的多样性和分布，特别是在农业景观中。它支持国家和欧洲红色名录的编制。尽管所有地点都位于传统玉米田内，但研究区域紧邻吕讷堡石南自然保护区，那里受威胁的石南景观中有珍稀的步甲物种，它们可能会从其边界处经过调整的农业管理策略中受益，甚至可能通过提供的合适廊道扩散。
